Dear Residents, This year marks the 30 th year that HIV and AIDS have been a part of our lives. HIV prevention and treatment efforts throughout Chicago have led to a 40% reduction in the number of HIV infections since 2000. The decline is due in part to collaborative efforts between the Chicago Department of Public Health (CDPH) and many local and national community partners. We are all committed to preventing the spread of HIV, early detection of the virus in people living with HIV, and the provision of a comprehensive system of prevention, care and support services. All of these efforts work together to reduce the burden of disease in Chicago and help ensure those living with HIV enjoy long, productive and healthy lives. Today, there are 20,391 people in Chicago living with HIV. As a City, while we have come a long way in the prevention and treatment of HIV and AIDS, there is still work to be done. Chicago is faced with the same challenges observed nationally, such as racial disparities and a younger population affected by HIV and sexually transmitted infections (STI). Through the framework set forth in the Healthy Chicago Public Health Agenda released earlier this year, the CDPH will remain committed to working with community partners to provide HIV and STI education, testing, diagnosis, treatment and support to all of our residents in need of services. HIV prevention is one of the top priorities outlined in the Healthy Chicago agenda and one of the main goals of the National HIV/AIDS Strategy. CDPH will continue to be a leader in HIV and STI education, prevention, and treatment to improve the health and well being of all Chicagoans. This report provides a detailed picture of HIV, AIDS and STIs in Chicago, along with insights into our successes and the challenges we face in the future. Using the Healthy Chicago Public Health Agenda as a blueprint, we are enhancing our efforts to track these diseases, developing new prevention and treatment intervention strategies, reinvigorating our existing programs and services, and stepping up our policy initiatives to make structural changes to the existing service delivery systems throughout Chicago. By 2020, Healthy Chicago s goal is to reduce the number of new reported cases of HIV by 25 percent. Together with our community partners, we can achieve this goal making Chicago a healthier city for residents in every neighborhood. Bechara Chouciar, M.D. Commissioner of Public Health

Overview Chicago, like most other large urban areas, has significantly higher rates of diagnosis of HIV and other sexually transmitted infections than the country overall. Chicago s 2009 HIV infection prevalence rate of 756.5 per 100,000 population is nearly three times greater than the national rate of 276.5 per 100,000. In 2009/2010 there were similar rates of AIDS and primary and secondary (P&S) syphilis diagnoses in Chicago and a higher rate of HIV infection. HIV and STI infections are prevalent among the same risk groups and have been reported to enhance the acquisition and transmission of one another. In 2010, 57% of men who have sex with men (MSM) who were diagnosed with P&S syphilis were co-infected with HIV. Coinfection analysis with other STIs shows that within two years of an HIV diagnosis, 1 in 13 persons acquired an STI. Both nationally and locally there are considerable racial/ ethnic disparities in STI/HIV rates. In Chicago, non-hispanic (NH) Blacks have an AIDS case rate that is four times greater than that of NH Whites, an HIV infection diagnosis rate three times higher and an HIV infection prevalence rate twice that of NH Whites. Hispanics have a considerably lower prevalence rate than NH Whites and NH Blacks and a slightly higher AIDS diagnosis rate than NH Whites. Compared to the U.S. the HIV prevalence rate is higher in Chicago for all race/ethnicity groups but the magnitude of difference varies. Most notable is the difference for NH Whites who have a prevalence rate five times greater than that of the US. Table 1.

HIV Trends There are currently 20,391 people living with HIV infection in Chicago. Estimating that 20% of people infected with HIV are unaware of their status, there could be over 25,000 people living with HIV in the city. AIDS diagnoses have declined considerably since the peak in the mid-1990s. The number of diagnosed AIDS cases increased slightly between 1998 and 2002 before steadily declining through 2009 (see Figure 1). From 1999 when HIV reporting began, the number of HIV infection diagnoses (which include new HIV diagnoses regardless of stage of the disease) was highest in 2001. Since then, the number of HIV diagnoses has been declining steadily. Overall, between 2000 and 2009, the number of HIV infections has declined 40%, from 1,830 in 2000 to 1,092 in 2009. The number of deaths among people living with HIV declined markedly in the late 1990s and have continued to decline, falling below 400 in 2008. Because there continue to be new HIV infection diagnoses every year and persons infected with HIV are living longer, the number of people living with HIV infection continues to increase every year.. Expanded testing initiatives citywide have contributed to more timely identification of HIV, thus reducing the number of late HIV infection diagnoses defined as an HIV and AIDS diagnosis within the same year..

Since 2003, the number of AIDS cases has declined by nearly 30%, from 921 AIDS diagnoses in 2003 to 649 diagnoses in 2009. The decline ocurred in both males and females but males continue to represent three out of every four AIDS diagnoses. All racial/ethnic groups in Chicago experienced a decrease in the number of annual AIDS diagnoses. However, NH Blacks continue to be disproportionately affected by AIDS. In 2009, NH Blacks accounted for 61% of AIDS diagnoses while NH Whites and Hispanics represented 15% and 19% of the diagnoses, respectively. While the number of annual AIDS cases has declined across all transmission groups, the largest decline occurred among injection drug users (IDU). From 2003 to 2009, the number of cases due to IDU fell by 48%. Year of Diagnosis However, men who have sex with men continue to represent the largest percentage of AIDS diagnoses, accounting for more than half of all cases in 2009. In 2009, one out of every four people diagnosed with AIDS were under the age of 30. The trend in annual number of AIDS diagnoses differed by age group. From 2003 to 2009, those aged 30-39 and 40-49 experienced the largest decline (48% and 37%, respectively). Slight increases were observed in the number of annual AIDS cases among those diagnosed between the ages of 20-29 (17% increase). As a result of these varying trends, there has been a shift in the age distribution of AIDS cases. Specifically, from 2003 to 2009, the percent of persons aged 30-39 decreased from 35% to 26% while the percent of 20-29 year olds increased from 13% in 2003 to 22% in 2009. STI/HIV Chicago 3

Table 3 From 2003 to 2009, the number of HIV infection diagnoses fell from 1,601 to 1,092, representing a 32% decrease. The decline is observed for all race/ethnicity groups, with a 29% decline among Blacks, 42% among Whites and 32% among Hispanics. During this time period, the decline was sharper for females (39%) than males (29%) which resulted in a slight increase in the proportion of male HIV infection diagnoses. In 2009, males represented approximately eight of every ten diagnoses. The largest decline in the number of HIV infection diagnoses among transmission groups occurred among IDUs (54%). Consequently, from 2003 to 2009, the percentage of IDU cases overall dropped from 18% to 12%. In 2009, male-to-male sexual contact was the leading mode of transmission (62%), followed distantly by heterosexual contact (21%). There have been considerable differences in HIV trends by age group. Between 2003 and 2009, the number of HIV infection diagnoses actually increased for those ages 13-19 and 20-29 (50% and 20%, respectively), while the older age groups all experienced declines. The largest decline (56%) was for those ages 30-39. Therefore, the proportion of cases under the age of 30 increased from 22% to 40%. STI/HIV Chicago 4

Table 4 While males account for 79% of all HIV infections, this percentage varies by race/ethnicity. Among NH Black diagnoses 71% are males, compared to 95% for NH White and 85% for Hispanic diagnoses. Among MSM who were diagnosed with HIV infection in 2009, 50% were NH Black, 27% were NH White and 18% were Hispanic. Male-to-male sexual contact is the leading mode of transmission for males diagnosed with HIV in 2009 for all race/ethnicity groups. Among NH White males, however, male-to-male sexual contact is the predominant mode of transmission (91% ). For NH Black males diagnosed with HIV, male-to-male sexual contact accounted for three quarters of all diagnoses and injection drug use (IDU) accounted for 12% of diagnoses. For Hispanic males diagnosed with HIV, male-to-male sexual contact accounted for 78% of all diagnoses and injection drug use (IDU) and heterosexual contact accounted for 8% and 9% respectively. Heterosexual contact accounts for nearly 74% of all HIV infection diagnoses among females for all race/ethnicity groups. While heterosexual contact is the leading mode of transmission for Hispanic women (67%), injection drug use is responsible for 33% of HIV transmissions. Adolescents and young adults up to 29 years of age represented 39% of HIV infections diagnoses in 2009. In this age group, male-to-male sexual contact is the predominant mode of transmission for males and heterosexual contact for females. People 50 and older represent 13% of 2009 HIV diagnoses. The leading mode of transmission in this age group is injection drug use, accounting for 34% of HIV diagnoses among women and 38% among men. STI/HIV Chicago 5

Includes perinatal transmission, blood transfusion and hemophilia. Table 5 Of the 20,391 people living with HIV infection, 79% are men, 52% are NH Black, and 57% are MSM. Among NH Black men living with HIV infection, 60% were infected as a result of male-to-male sexual contact, and 22% as a result of injection drug use. As observed with HIV diagnoses, the majority of NH White men were infected primarily through male-to-male sexual contact (90%). Male-to-male sexual contact accounted for approximately 3 out of every four (74%) living HIV cases among Hispanic men. Overall, male-to-male sexual contact was the leading mode of transmission among males living with HIV infection (72%), while heterosexual transmission was the leading mode of transmission among women (63%). In both males and females living with HIV, IDU was the second leading mode of transmission (13% in males, 33% in females). Of all people living with HIV 12% are under the age of 30. In this age group, male-to-male sexual contact is the predominant mode of transmission for males and heterosexual contact for females. Nearly 33% of men and 27% of women living with HIV infection are currently over the age of 49. The leading mode of transmission in this age group is male-to-male sexual contact (58%) for men while for women it is both heterosexual contact (51%) and injection drug use (49%). STI/HIV Chicago 6

Table 8 In 2010, gonorrhea cases decreased by 28.3% compared to 2009, after two years of increases. Decreases in the morbidity partially could be explained by implementation of the new STI Surveillance system and changes within the STI surveillance data submission from private as well as public providers. In 2010, the total number of reported cases for those ages 20-24 was almost twice the number of reported cases for those 25-29 years of age. More than 67% of cases occurred among people younger than 25 years of age. Males and females are almost equally affected by gonorrhea (46% of males and 54% of females were diagnosed with gonorrhea in 2010). Nearly 67% of 2010 gonorrhea cases were NH Black. NH Whites comprised 5% and Hispanics comprised just 4% of total gonorrhea cases in 2010. Approximately 23% of cases were reported with unknown race/ethnicity making interpretation difficult.

Table 10 Three-quarters of Chlamydia reports are among females, both in Chicago and in the US overall. This sex disparity is likely a surveillance artifact resulting from the fact that screening guidelines target females almost exclusively, and reflecting differential patterns of health care utilization by women and men. As was the case with gonorrhea, most Chlamydia cases were in NH Blacks (58%). NH Whites and Hispanics comprised just 16% of cases. Again, note that race/ethnicity is missing for approximately 24% of cases making data interpretation difficult. Overall, 86% of Chlamydia cases occurred in individuals under the age of 30. Approximately 70% of cases were among persons less than 25 years of age. STI/HIV Chicago 14

Table 12 Between 2009 and 2010, primary and secondary (P&S) syphilis cases increased by 23% (22% among NH Whites, 59% among NH Blacks and 13% in Hispanics). In 2010, the overwhelming majority of P&S syphilis cases were in men (88%), reflecting the continuing syphilis epidemic among men who have sex with men (MSM). Between 2009 and 2010 the number of P&S syphilis cases in MSM slightly decreased (by 1.5%). However, 26% of the cases were reported as male with unknown gender of sex partner which, if known, could impact the magnitude of the MSM epidemic. Between 2009 and 2010 the number of P&S syphilis cases among females and heterosexual males increased by 171% and 115%, respectively. In 2010, the highest proportion of P&S syphilis cases occurred in NH Blacks (59%) and in those ages 20-29 (38%). Since MSM sexual contact is the leading mode of HIV transmission in Chicago, syphilis and HIV share similar routes of transmission. Infection with either disease increases the likelihood of transmitting or acquiring the other from an infected partner.
